Abstract According to the 2018 National Air Pollutant Emissions Inventory (NEI), air pollutant emissions in Republic of Korea comprised 808,801 tons CO, 1,153,265 NO X , 300,979 SO 617,481 TSP, 232,993 PM 10 98,388 2.5 15,562 black carbon (BC), 1,035,636 VOCs, and 315,975 NH 3 . As for national emission contributions primary precursors (NO ), major source categories were road sector industry everyday activities others VOCs In case by region, largest amount was emitted from Seoul Metropolitan Areas (SMA; Seoul, Incheon, Gyeonggi-do, hereafter SMA) amounts Yeongnam region. A 3D chemical transport modeling system used examine uncertainty based on Emission Quality Assessment System (NEAS). quality simulated using CAPSS 2018, simulation data compared with observed concentrations uncertainties current emissions. These show that five si (cities) (Pohang, Yeosu, Gwangyang, Dangjin, Ulsan) need be improved. Most all, it is necessary places business use anthracite, which source, as fuel these areas.
